Referring to fig. 1 to 7, the present application provides a child safety seat, which includes a seat 100, a base 200, and support legs 300, wherein the seat 100 includes a cushion part 110 and a backrest part 120. The base 200 is used for bearing the reclining body 100 and has a front part 201 and a rear part 202 which are opposite, the front part 201 is provided with a connecting seat 400 which can slide and stretch, and a locking piece 510 which limits the sliding of the connecting seat 400, and the locking piece 510 has a locking state which limits the sliding of the connecting seat 400 and a releasing state which allows the sliding of the connecting seat 400.

The rear portion 202 of the base 200 is provided with a connection 410 for connecting to a car seat, which in this embodiment is an ISOFIX interface.

Regarding the support leg 300, which is rotatably connected with the connection seat 400 and has a substantially vertical use state and a storage state of being rotated close to the base 200, when the support leg 300 is switched from the use state to the storage state, the locking piece 510 is driven to be switched to the release state so as to release the movement restriction of the connection seat 400.

Connecting seat 400 slides forwards and stretches out of base 200, supporting leg 300 rotates and switches to the user state, and locking piece 510 switches to the locking state simultaneously, has satisfied the length demand that supporting leg 300 was located when the user state. When the support leg 300 rotates to switch to the storage state and drives the locking member 510 to switch to the unlocking state, the connecting seat 400 can slide and retract into the base 200, so that the connecting seat 400 is invisible at least in a top view angle, thereby shortening the length of the base.

The utility model provides a child safety seat's overall dimension is in the smaller than current under the state of accomodating at the supporting leg, does benefit to the packing and accomodates. And the sliding of the connecting seat 400 is controlled by the storage operation of the supporting leg 300 in a linkage manner, and the operation is more reasonable without additionally pressing and unlocking. And the supporting leg 300 is limited in the using state, so that the leaning body 100 and the base 200 are prevented from sliding forwards relative to the supporting leg 300 in the driving process of the automobile, and the automobile is safer.

Referring to fig. 11-14, in one embodiment, the two locking members 510 are disposed opposite to each other, and the two corresponding locking grooves 210 are disposed on the two sidewalls 221. When the locking members 510 are unlocked, they are close to each other, and an elastic member 520 (e.g., a spring) is disposed between the locking members 510 to urge them to return (away from each other and inserted into the locking groove 210).

In one embodiment, the locking member 510 is a hollow structure made of a material such as a hard plastic material, which facilitates processing in various shapes, and improves locking strength for safety. The locking member 510 is provided with a reinforcing member 530 inside. Preferably, the reinforcing member 530 has a solid structure; preferably, the reinforcing member 530 is made of hard metal, or in this embodiment, the reinforcing member 530 is a solid cylinder made of hard metal embedded in the locking member 510, and two ends of the elastic member 520 are abutted against the reinforcing member 530, so that the reinforcing member 530 is prevented from being removed.

In one embodiment, the front portion 201 of the base 200 is provided with an unlocking member 540 triggered by the support leg 300 to drive the locking member 510 to unlock, wherein the unlocking member 540 is slidably disposed in the connecting seat 400.

In combination with the rotation direction of the support leg 300 being in a vertical plane and the sliding direction of the lock 510 being perpendicular to the vertical plane, the sliding direction of the unlocking member 540 is preferably perpendicular to the sliding direction of the lock 510, that is, the support leg 300 is unlocked by abutting against and pushing the unlocking member 540 to slide during the rotation process.

Referring to fig. 15 and 16, in an embodiment, a slope 501 is provided between the locking member 510 and the unlocking member 540, which cooperates to drive the locking member 510 to unlock, so as to change the sliding direction.

Referring to fig. 6, 7 and 17-20, in an embodiment, the connecting socket 400 includes a housing 440 and a core 450, the housing 440 includes a top plate 441 and two side wings 442 arranged in parallel, the core 450 is arranged in a space 443 defined by the top plate 441 and the side wings 442, and the locking member 510 is slidably mounted on the core 450. Inner core 450 can be the plastics material, and shell 440 is the metal sheet bending type, and the structural strength of connecting seat 400 is improved in the intercombination, and weight reduction satisfies the installation demand of locking piece 510 simultaneously.

Depending on the strength of the housing 440, in one embodiment, the support leg 300 is pivotally connected to the wing 442, and the wing 442 is provided with a first rotation stop surface 310 for preventing the support leg 300 from being turned over excessively.

In order to prevent the support legs 300 from being folded accidentally, in one embodiment, the child safety seat further includes a protective cover 600 covering the connection seat 400 and the connection between the connection seat 400 and the support legs 300, so that the appearance is more concise, and the rotation of the support legs 300 is prevented from being blocked due to impurities falling into the connection. The protective cover 600 is provided with a second rotation stop surface 611 which cooperates with the first rotation stop surface 310 to keep the support leg 300 in the use state.

In the illustration, the support leg 300 is provided with a limiting post 320 abutting against the first rotation stop surface 310 and the second rotation stop surface 611. The inner wall of the protecting cover 600 is convexly provided with a limiting block 610, the rear end surface of the limiting block 610 is a second rotation stop surface 611, and the front end surface is a guide inclined surface 612 for guiding the limiting column 320 to enter between the first rotation stop surface 310 and the second rotation stop surface 611. When the protective cover 600 is rotated to be stored, sufficient external force is applied to the supporting leg 300, the limiting block 610 is pushed open by the limiting column 320, and the protective cover 600 is driven to deform to release the interaction with the first rotation stopping surface 310 and the second rotation stopping surface 611.

Referring back to fig. 6 and 7, in one embodiment, the core 450 includes a mounting base 451 and a cover 452 that snap fits over the bottom of the mounting base 451, and the side wall of the unlocking member 540 is provided with a stop against the cover 452 to limit the core from falling off.

In one embodiment, the protective cover 600, the outer shell 440 and the inner core 450 are fixed by the guide posts 420 in the previous embodiments.

Referring back to fig. 4, 5, 9 and 10, in addition to maintaining the support leg 300 in the use state, in one embodiment, the sidewall 221 of the escape groove 220 is protruded with a rib 223 for engaging with the support leg 300 to maintain the storage state. During the forced rotation of the support leg 300, the ribs 223 are pressed to be deformed so as to pass over the ribs 223.

The whole size of this application children's safety seat is in the present littleer under the state of accomodating at the supporting leg, does benefit to the packing and accomodates. And the sliding of the connecting seat is controlled by the storage operation of the supporting legs in a linkage manner, the unlocking is not required to be additionally pressed, and the operation is more reasonable. And the safety of the supporting legs in the use state is limited, and the forward sliding of the leaning body and the base relative to the supporting legs in the vehicle form process is avoided.
